    High-Pressure Stainless Steel Unthreaded Pipe Flanges

    Use these heavy duty forged flanges for high-pressure applications. Bolt two flat-surface flanges or two raised-surface flanges of same size together with a gasket (sold separately) to create an access point in a pipe line.

    Stub End with

    Straight Adapter

    (Front)

    Forged flanges have better strength than cast flanges.
    Stub-End Fitting Connection—Stub-end flanges are also known as lap-joint flanges. Use them with a stub-end straight adapter (not included). The stub-end straight adapter slides into the flange and welds to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily for frequent cleaning and inspecting.
    304/304L Stainless Steel—Flanges hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.
    316/316L Stainless Steel—Flanges are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel flanges, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

    Drain, Waste, and Vent ABS Pipe Flanges for Chemicals

    These Schedule 40 flanges are an economical choice for gravity-flow chemical waste systems. Flanges are ABS plastic, which has excellent strength and impact resistance and good chemical resistance. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. They have socket-connect ends that attach to unthreaded pipe or another socket-connect fitting with ABS cement (also known as solvent weld). They meet ASTM D2661, ASTM D3311, ASTM D3965, and ASTM F1498 specifications and testing requirements for material quality and product dimensions.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

    Fiberglass Pipe Flanges for Chemicals

    Flanges have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. They are reinforced with fiberglass layers for better strength and durability than any of our other pipe flanges for chemicals. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges meet ASTM D4024 specifications and testing requirements for product dimensions, performance, and material quality.
    To connect flanges to pipe, first sand the inside of the flange and the end of the pipe to remove the surface finish. Next, mix the adhesive (sold separately) until the color is uniform with no streaks. Apply a thin layer of mixed adhesive to the sanded area of the pipe, approximately 1/8" thick. Repeat this process with the inside of the flange, applying a layer approximately 1/16" thick. After sealant has been applied, push the flange onto the pipe until it is fully engaged. Make sure you align the bolt holes prior to installing to minimize rotation after the flange is installed. Finally, use the adhesive-curing heat cable (sold separately) to cure the adhesive. Wrap the tape around the pipe and flange at the joint, taking care to not overlap the tape. Once you have waited the full cure time, the pipe and flange will be ready to use.

    Stub-End Fitting Connection—Stub-end flanges are also known as lap-joint flanges. Use them with a stub-end straight adapter (not included). The stub-end straight adapter slides into the flange and welds to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily for frequent cleaning and inspecting.

    Straight Adapter

    Stub-end straight adapters are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.

    Thick-Wall Plastic Pipe Flanges for Water

    Also known as Pressure Class 150 flanges, these flanges have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They meet NSF/ANSI 61 for drinking water. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. All are PVC, which has good corrosion resistance. Some are also glass filled for extra durability. They meet ASTM D1784 specifications and testing requirements for material quality.
    To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

    FM-Approved Low-Pressure Iron and Steel Unthreaded Pipe Flanges

    FM-approved for fire protection applications, these flanges are cast iron, so they're brittle and can be quickly opened by hitting them with a sledge hammer. Bolt them together with a gasket (not included) to create an access point within a low-pressure pipe line. All are cap flanges, which are also known as blind flanges. Use them in noncorrosive environments.

    Front

    Made of PTFE, these flanges can handle a wider temperature range than any of our other plastic pipe flanges for chemicals. They have the chemical resistance to stand up to acid and solvents. Also known as Pressure Class 150 flanges, they have thick, strong walls for heavy duty industrial applications. The material won’t leach contaminates into the line, so these flanges are commonly used in high-purity processes, such as semiconductor and clean room applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line.
    To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns. Flanges meet ASTM D1710 specifications and testing requirements for material quality.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

    Drain, Waste, and Vent Standard-Wall PVC Pipe Flanges for Water

    Also known as Schedule 40 flanges, these are the industry standard for gravity-flow drain, waste, and vent (DWV) applications. They are PVC for good corrosion resistance. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. They have socket-connect ends that attach to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld). Flanges meet ASTM D1784 and ASTM D2665 specifications and testing requirements for material quality.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

    Flame-Retardant PVDF Pipe Flanges for Harsh Chemicals

    Flanges meet UL 94 V-0 for flame retardance to delay the spread of flames to valuable equipment. They are made of PVDF (polyvinylidene fluoride), which is comparable to Kynar, and has the chemical resistance to stand up to solvents and other harsh substances. Also known as Pressure Class 150 flanges, they have thick, strong walls for heavy duty chemical processing applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line.
    To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns. Flanges meet ASTM D3222 specifications and testing requirements for material quality.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

    High-Purity Polypropylene Pipe Flanges for Drinking Water

    The inside of these flanges won’t leach contaminants into your line or accumulate particles—they’re polished to an ultra-smooth 12 Ra finish, which also makes them easy to clean. Made of polypropylene, they resist organic solvents, acids, and alkalis better than CPVC pipe flanges. Bolt two same-size flanges together with a gasket (not included) to create an access point in your line. These flanges meet NSF/ANSI 61 for use with drinking water, and they’re FDA compliant for direct contact with food. They also meet ASTM requirements for material and performance, and ISO requirements for dimensions.
    Also known as lap-joint flanges, they connect to pipe with stub-end straight adapters (not included). Slide the stub end adapter into your flange and weld to your pipe with socket fusion. Since the flange isn’t welded to the pipe, it can be disconnected easily for cleaning and inspecting.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

    UV-Resistant Polypropylene Pipe Flanges for Chemicals

    Use these polypropylene flanges in outdoor environments—they resist the damaging effects of ultraviolet light. Flanges have the chemical resistance to stand up to a wide variety of acids, solvents, and other harsh substances. Also known as Pressure Class 150 flanges, they have thick, strong walls for heavy duty chemical processing applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line.
    To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.
